Why this could be an opportunity

Low confidence1 independent sourceLead to verifyListing checked 3 Nov 2026

This rests largely on a single source. Treat the score as a prompt to investigate, not a conclusion.

Check before relying on this score: the estimate sits 22% above the ask; lead to verify: leasehold with no service charge disclosed - the stress test assumes GBP 0. It ranks after every home whose inputs are verified.

Valuation edge2.5/15
claims [AVM +22.1% (MEDIUM), sold-comps +43.1%, £/sqft +43.2%] → measured edge +0.50pp of the ask; on later-registered sales an AVM discount carried no edge and a sold-evidence gap at most +0.5pp

4 of 4 components scored. Ranks on gross yield, the stress margin, risk and disclosed facts. A pricing claim earns only its measured edge: today 0 for the market estimate and at most +0.5pp for sold evidence. The score itself is not yet checked against the outcomes of homes it scored.

Economics

What happens to your money

Price sensitivity

£71,000£109,000

The same scorer re-run at hypothetical asking prices, holding rent, comps and listing history constant. Not a prediction of what the seller would accept.

Your assumptions

Purchase price£95,000

At the asking price

Monthly rent£600/mo

Evidenced range £550-£650

Interest rate5.4%

Loan to value75%

Cash required: £29,800
Net cash flow: £95/mo
Cash on cash: 3.8%
Score at this price: 33

After a 8% void allowance, 15% management and 10% maintenance. Lender coverage (rent ÷ interest): 1.87 - clears the usual 1.25 test. These are your assumptions, not evidence: only the pre-filled rent and price come from the record.

Risks

What could kill this deal

Score confidence is low
largely a single source - treat the number as a prompt, not a conclusion
Rental economics needs verification before you rely on it
rent estimate 600/mo (range 550-650)
Rental economics needs verification before you rely on it
sale estimate 22% above the ask on the same snapshot - verify the rent describes this home

Plan

Before you offer

1. Get two written rental appraisals from local lettings agents.
The market estimate this rent rides on sits far above the asking price, so the rent may describe a different home.
2. Ask the agent why the price was reduced and whether a previous sale fell through.
1 price cut(s) recorded on the listing history.
3. Treat the gap to the estimate as unproven - compare recent sold prices on the street yourself before pricing an offer around it.
On later completions, homes listed below their estimate sold at the same share of the asking price as the rest.
4. Commission a full structural survey, not a basic condition report.
The score prices market evidence, not the fabric of the building.
